Sasha's balance after 12 years, if she makes no other deposits or withdrawals would be $ 4, 598. 07

Sasha's balance after 12 years will be the future value of her savings after 12 years at a rate of 2. 3% per year.

This future value can be found by the formula :

Amount after 12 years = Amount deposited by Sasha x ( 1 + annual compound interest ) ^ number of years

= 3, 500 x ( 1 + 2 .3 % ) ¹²

= 3, 500 x 1.3137344983996021269289886802331

The value of m in the equation m=-(4+m)+2 is -1.

How are linear equations solved step-by-step?

One of the easiest methods for resolving a system of linear equations is graphing. Simply plot each equation as a line on a graph and identify the point or points where the lines converge to find the value. These equations are simple to graph because they are already expressed in slope-intercept form.

m = -(4+m)+2

m = -4 -m + 2

m = -2 - m

m + m = -2

2m = -2

m = -1

Hence, the value of m in equation m=-(4+m)+2 is -1.

Answer:

The first one, due to the x being raised to the power of 2

Step-by-step explanation:

The equation of a line that represents the table is y = 6x - 5.

We know lines have various types of equations, the general type is

Ax + By + c = 0, and the equation of a line in slope-intercept form is

y = mx + b.

Where slope = m and b = y-intercept.

the slope is the rate of change of the y-axis with respect to the x-axis and the y-intercept is the (0,b) where the line intersects the y-axis at x = 0.

To obtain the linear equation first we need slope(m) = (y₂ - y₁)/(x₂ - x₁)

= (1 + 11)/(1 + 1) = 12/2 = 6.

Now, we'll take any one of these coordinate points and construct an equation in slope-intercept form,

- 11 = 6(-1) + b.

- 11 = - 6 + b.

b = - 5.

∴ y = 6x - 5 is our equation.

What is two point equation form?

The equation of the line passing through two points is

The box plot indicates that the interquartile range (IQR) of the data 0, 25, 50, 75, and 100 is 100.

Find the median (middle value) of the bottom half and upper half of the data before calculating the interquartile range (IQR). Quartile 1 (Q1) and Quartile 3 are these values (Q3). The IQR represents the variation between Q3 and Q1. We use the median to summarize a typical value rather than the mean when a data collection contains outliers or extreme values. The interquartile range, which is the difference between the first and third quartiles, is a statistic that is frequently used to summarize variability in data sets with outliers.

Here,

The first and third quartiles would need to be located initially. Then, to obtain the IQR, you would divide the third quartile by the first.

Solution set of the equation is -3,-1, and 2 by simplifying the equation we get m³+2m²-5m-6 = 0

There are many different ways to define an equation. The definition of an equation in algebra is a mathematical statement that demonstrates the equality of two mathematical expressions. For instance, the equation 3x + 5 = 14 consists of the two equations 3x + 5 and 14, which are separated by the 'equal' sign.

Mathematical algebraic equations typically have one or more variables.

Given equation is: (6/m)+2 = (m+3)(m-1)

multiply with m both sides,

⇒6+2m = m(m²+2m-3)    

⇒m³+2m²-3m = 6+2m

So we get,

m³+2m²-5m-6 = 0

Solving we get, m = -3, m = -1, m = 2 as solution of given equation.

Given that;

Two points on the coordinate plane are C = (-9, 7) and Q = (-1, 3).

Now,

Since, Two points on the coordinate plane are C = (-9, 7) and Q = (-1, 3).

Hence, The distance between the points C = (-9, 7) and Q = (-1, 3)  in the coordinate plane will be;

⇒ D = √(3 - 7)² + (- 1 - (-9))²

the center of the circle is at (5, 1) and the radius is approximately 5.48 units.

Why it is and what is perimeter of a circle?

The standard equation of a circle with center (a,b) and radius r is:

(x - a)²2 + (y - b)²2 = r²2

Comparing this equation to the given equation, we can see that the center of the circle is (5, 1) and the radius is the square root of 30. Therefore, the center of the circle is at (5, 1) and the radius is approximately 5.48 units.

The perimeter of a circle is also known as its circumference, and it can be calculated using the formula:

C = 2πr

where C is the circumference, r is the radius of the circle, and π (pi) is a mathematical constant approximately equal to 3.14159.
